Workshop objectives
Workshop Objectives

  • An overview of technical capacity

  • The methods for assessing technical capacity

  • The importance of source water and infrastructure adequacy to technical capacity

  • The benefits of assessing and maintaining technical capacity


Fundamental goals of capacity development
Fundamental Goals of Capacity Development

  • To ensure consistent compliance with drinking water standards

  • To enhance water system performance

  • To promote continuous improvement


What is capacity
What is Capacity?

  • Water system capacity is the ability to plan for, achieve, and maintain compliance with applicable drinking water standards

  • For a water system to have “capacity” it must have adequate capability in three areas: technical, managerial, and financial


Capacity elements
Capacity Elements

  • Each capacity element – technical, managerial, and financial – is necessary but not sufficient

  • Many aspects of system operation involve more than one capacity element

  • Each element is important to ensure the protection of public health and meet the requirements of the Safe Drinking Water Act (SDWA)
